Title: Gas cutoff valve
Inventor: OHASHI NORIYOSHI
IPC: F23N1/00
Filed: 1988-05-24
Abstract: PURPOSE:To obtain a gas cutoff valve of reliability at a low cost by accurately working a core piece by a beveled steel which is easily cut and covering with a cap obtained by pressing a stainless steel having magnetized attraction face requiring no corrosion resistance processing. CONSTITUTION:At the time of abnormality, when an electromagnetic coil 6 is instantaneously energized so as to generate a magnetic fluid in a direction opposite to a permanent magnet 2, a magnetic force is generated by the electromagnetic coil 6 so as to reduce attraction force between a cap 16 and a plunger 9. According to this magnetic force, the attraction faces of the cap 16 and the plunger 9 are separated to interrupt a gas passage by a valve rubber 10. The cap 16 made of magnetic stainless steel is covered on a core piece 3 made of beveled steel, thereby, a valve can be assured for ten years. Since the core piece 3 can be changed to the beveled steel of one chuck and easy in a cutting work by providing the cap 16, the cost can be lowered.

IPC: H01L21/331
Filed: 1992-05-20
Abstract: PURPOSE:To eliminate the decrease of the junction withstand voltage between an emitter and a base which decrease is to be caused by the position deviation of an active base in the course of a manufacturing process, by forming a diffusion layer between the active base and the inactive base of a transistor part which layer has the concentration between that of the active base and that of the inactive base. CONSTITUTION:A so-called link base diffusion layer 108 is formed between the active base layer 112 and the inactive base layer 111 of a transistor which layer 108 has the concentration between that of the layer 112 and that of the layer 111. For the above purpose, after polycrystalline silicon 114 is selectively oxidized, the left polycrystalline silicon 114 is used as a diffusion source, and a P-type diffusion layer 108 is formed in a substrate. Further oxidation is performed and polycrystalline silicon 115 is used as a diffusion source, thereby forming a P-type layer 111 whose concentration is higher than the P-type layer 108. Thus the inactive base layer 111 of high concentration is made distant from an emitter layer 116, and a structure can be realized wherein the active base layer 112 is in contact with the inactive base layer 111 via the same P-type layer.
